The Matriarch
From Tardis Wiki, the free Doctor Who reference
The Matriarch was the artificial intelligence of a Craw spacecraft which crashed into England in the 12th century. It became active again after George Colbert killed Mike, Penny, Albie and Samantha Tungate and used Harri to communicate with the Seventh Doctor, Ace and Thomas Hector Schofield. (AUDIO: Displaced)
